A burning smell reported across Singapore on Feb. 13 may be attributed to smoke from peatland and vegetation fires in the surrounding region, according to the National Environment Agency (NEA).
Singapore Air Quality and Regional Fires
The NEA stated that fires release a complex mixture of gases that can create a noticeable burning smell, even at low concentrations.
Showers are forecast for Singapore and neighboring areas in the coming weeks. However, the region is currently experiencing a dry phase of the northeast monsoon, raising the possibility of extended dry periods.
Prolonged dry spells could lead to increased hot spot activity and a risk of smoke haze. Cloud cover on Feb. 13 limited satellite observation of potential hot spots.
As of Feb. 13, the 24-hour Pollutant Standards Index readings in Singapore were within the good to moderate range. One-hour PM2.5 levels were also normal, with a peak reading of 20 in eastern Singapore at 8 p.m.
PM2.5 refers to fine inhalable particles measuring up to 2.5 micrometers in diameter. Air quality is considered “normal” when PM2.5 readings range from zero to 55.
The NEA will continue to monitor the air quality and provide updates as needed. The public can access the latest information through the myENV mobile app.
Minister for Sustainability and the Environment Grace Fu noted on Feb. 12 that hazy conditions may occur in the coming weeks due to intensifying regional hot spot activity and changing wind patterns.
Should conditions worsen, the Haze Task Force, comprising 28 government agencies and led by the NEA, will implement measures to protect public health, particularly for vulnerable groups including the elderly, pregnant women, children, and individuals with chronic lung or heart conditions.
These measures include ensuring an adequate supply of N95 masks and deploying air purifiers in locations frequented by vulnerable populations, such as schools and nursing homes.
